EDMOND GUERI N, OF MAISONNEUVE, QUEBEC, CANADA.

FLUID-PRESSURE MOTOR.

Specification of Letters Patent.

Patented Dec. 1, 1914.

Application filed April 9, 1914. Serial No. aaasve.

To all whom it may concern:

Be it known that I, EDMOND GUERIN, a subject of the'King of GreatBritain, res1ding at No. 128 Bourbonniere street,Maisonneuve, Provinceof Quebec, Canada, have invented certain new and useful Improvements inFluid Pressure Motors; and I do hereby declare that the following is afull, clear,

' panying drawings forming part of the prescat application.

Throughout the several figures of the drawings like reference charactersdesignate the same parts.

In the drawings: Figure 1 is a top plan view of the invention, partlybroken away; Fig. 2 is a fragmentary side elevation of the lower end ofFig. 1, inverted; Fig. 3 is a plan view of the rack drive; Fig. 4 is anenlarged, central, longitudinal, cross section through the valvechamber; Figs. 5 and 6 are enlarged, lateral, cross sections through thevalve chamber showing simultaneously feed and exhaust of the twocylinders; and

Figs. 7 and 8 are like views with the feed and exhaust reversed.

. The main objects of the invention are to provide a simple, efficient,economicahdurable, and compact fluid operated motor having a simplevalve mechanism automatically operated through mechanism actuated by themovements of the pistons.

Referring to the drawings in detail, 1 indicates head or end plates eachprovided with two cylinder heads and adapted to be drawn into operativeclamping position on the ends of a pair of cylinders 2, by means ofclamping rods 3. One of the head or end plates is provided with a box,casin ,'or,

casting 4 in which is provided a valve c amber having inlet and exhaustpassages 5 and 6, respectively, for supplying pressure feed permittingit to escape therefrom. Delivery and exhaust passages 7 and 8 lead fromthe valve chamber to each of the cylinders. Within the valve chamber ismounted an oscillating cylindrical plug valve 9 having two similarsegmental cavities 10 and 11 on diametrically oppositesides and near thelower end, and a third similar segmental cavity 12 extending at rightangles to the first cavities and arranged near the upper end of thevalve. The

outer end or spindle of the valve is provided with a short rod 13adapted to be engaged by a fork 14 on the endof the long arm of a Ylever 15 pivoted at 16 on a plate 17 supported by and secured to the endplates or heads. The short arms of the lever are each provided with apin or the like playing -fre'ely through a substantially triangularopening in theend of the cylinder and adapted to be engaged by the usualpistons as they approach the outer ends of their strokes, thus causing arocking motion of the Y lever. It is advisable, of c0urse,,to main tainthe Y lever in each of its two opposite positions until the instant thatit is to be shifted. For this pur ose, the lon arm is extendedlongitudinal y between t e short arms and is provided with a V-shapedsocket :17? adapted to receive one end of a small plate 18, the oppositeend of which is similarly seated in a corresponding notch 19 formed inthe projecting end of a small block 20 which is slidably mounted in atubular or other shaped box or casing 21. A coil spring 22, withincasing 21, acts to maintain the block in operative engagement with theplate 18, and a set screw 23 is used to adjust the force of the springon the block. An ear 24 extending from the adjacent end or head supportsthe casing 21 and also forms a rest for the lower edge of the plate 18to prevent it from dropping out of the notch or socket. The same headmay also be provided with a second ear or the like 25 for attachment toa suitable support.

As will be clear on reference to Fig. 1,

pinion 28 secured to a suitable driving shaft for, operating a washingmachine or any other suitable apparatus.

It is thought that the construction, operation, and use of the inventionwill be clear from the preceding detailed description.

Changes may be made/in the construction, arrangement, and disposition ofthe several parts of the invention without in any way departing from thefield and scope of the same, and it is meant to include all such withinthis application wherein only a pre ferred form has been disclosed.

Having thus fully described my invention, what ll claim as new anddesire to secure by Letters Patent is:

1. An apparatus of the character described comprising two cylinders,pistons reciprocably mounted therein, a Y lever actuated by said pistonsand provided with a yoke, an oscillating plug'valve adapted to controladmission and exhaust of pressure fluid to and from said cylinders,and arod carried by said valve and adapted to be engaged and actuated by saidyoke.

2. An apparatus of the character at scribed comprising, two cylinders,pistons reciprocable therein, a valve for controlling admission andexhaust of pressure fluid to and from the cylinders, a V lever operatedby said pistonsand. adapted to actuate said valve, said Y lever beingprovided with an v Lilia-tea extension having a socket, aslidably'mo'unted spring actuated block provided with a notch, and aplatehaving its opposite ends seated in the aforesaid socket and saidnotch, respectively.

w 3. In valve gear adapted to be by a double cylinder engine, a Y leverhaving its diverging arms, respectively connected to the piston rods ofsaid engine and alternately thereby actuated, an oscillating valveconnected loosely t o the long arm of operated said lever and alsoconnected to said valve,

an arm of saidlever extending upward and having a ll-shaped recess inits end, a spring pressed part above the same having an opposedsimilarly formed recess, and a plate EDMOND GUERINQ Witnesses 1 A.lBas'rmlt, ARTHUR Durnnsnn.
